Virion Properties

Morphology

Virions consist of an envelope, a surface membrane, a core, and lateral bodies, or a surface membrane, a core, and lateral bodies. During their life cycle, virions produce extracellular particles and produce intracellular particles; can occur in two phenotypes; may be enveloped during their extracellular phase. The infection is initiated by extracellular virions. Virus may be sequestered within inclusion bodies that are not occluded and typically contain one nucleocapsid. Virus capsid is enveloped and mature naturally by budding through the membrane of the host cell; brick-shaped to pleomorphic. Virions measure 200 nm in diameter, or 260-280 nm in diameter; 330-350 nm in length displaying tubular units. The core is biconcave with two lateral bodies. Lateral bodies are lens-shaped. Nested between the core membrane, or between the surface membrane. Contains a folded nucleoprotein thread.

Additional electron micrograph of Poxviridae are found in the Picture Gallery.

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.23-1.27 g cm^-3.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear double-stranded DNA. The complete genome is 130000-150000 nucleotides long. The genome has a guanine + cytosine content of 35 %. The genome sequence has termini with cross-linked hairpin ends (i.e. single- stranded loopes thus forming one continuous polynucleotide chain). The genome has terminally redundant sequences. The terminally redundant sequences have reiterated inverted terminal sequences which are tandemly repeated; are reiterated internally. The genome sequence is repeated at both ends. Double-stranded DNA is covalently. Double-stranded DNA is linked at both ends.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are present and located in the envelope. Virions are composed of 4% lipids by weight. The composition of viral lipids and host cell membranes are similar. The lipids are host derived and synthesized de novo (during the early phase of virus replication) and are derived from plasma membranes. Viral membranes include glycolipids.

Biological Properties

The description has been generated automatically from DELTA files.

ICTVdB - The Universal Virus Database, developed for the International Committee on Taxonomy of Viruses (ICTV) by Dr Cornelia Büchen-Osmond, is written in DELTA. The virus descriptions in ICTVdB are coded by ICTV members and experts, or by the ICTVdB Management using data provided by the experts, the literature or the latest ICTV Report. The character list is the underlying code. All virus descriptions are based on the character list and natural language translations from the encoded descriptions are automatically generated and formatted for display on the Web.
